Apparatus and process for preparing alloy sheet

Abstract

This invention relates to alloy slice process method and device, wherein the method comprises the following steps: flowing the alloy melt liquid to one cooling cylinder surface to form thin slice band; the alloy slice gets cooled during deliver process; continuing cooling and grinding when the alloy slice gets the collector; entering the materials sending structure form collector and keeping cooling in inert gases protection. The device comprises one container put in the inductance heating coil; one liquid stable structure located down the container mouth; one cooling cylinder moving back and forth along axis; one deliver structure; one collector located above the deliver structure; one materials sending structure.

Description

technical field [0001] The present invention relates to a preparation device and a manufacturing process of alloy flakes. Specifically, it is a device for discharging alloy flakes in batches while casting alloys containing rare earth and other easily oxidizable metals through vacuum induction melting and multi-stage rapid cooling. craft. Background technique [0002] Rare earth metals and their alloys are usually very easy to oxidize, and the alloy flakes of such materials are usually prepared by vacuum induction casting. figure 1 Shown (see Japanese patent application level 11-177426 patent specification for details). figure 1 Since the drum 5 does not move axially, in order to cool the melt 2 evenly and rapidly across the entire width of the drum 5, there must be a storage of melt in the tundish 4 to slow down the flow rate and spread the melt evenly across the width of the nozzle. , This process leads to the end of casting, the melt is easy to solidify at the nozzle and...

figure 1 Since the drum 5 does not move axially, in order to cool the melt 2 evenly and rapidly across the entire width of the drum 5, there must be a melt storage in the tundish 4 to slow down the flow rate and spread the melt evenly across the width of the nozzle. , this process leads to the end of casting, the melt is easy to solidify at the nozzle and block the nozzle, thus affecting the next normal use

Of course, the method of heating the tundish can be used to avoid possible blockage of the nozzle, which will complicate the structure of the tundish; The heat on the surface is too late to dissipate, and the temperature will rise slowly, resulting in the melt being cast before and after the same cooling conditions, which will affect the uniformity of the alloy strip

[0003] In addition, in the traditional device, although the container 7 for collecting alloy flakes at the bottom can be cooled by a water cooling device, the alloy flakes inside cannot be cooled sufficiently, and the temperature is still very high. For easily oxidized alloys such as rare earths, in It is very easy to oxidize during the transfer process, and it takes a long time to wait for it to cool down naturally. For large-scale continuous production, the efficiency is low
